VN/PRE TLC
This removes an always true parameter of vn_nary_op_insert_into and moves
valueization to the two callers of vn_nary_op_compute_hash instead of doing it
therein where this function name does not suggest such thing.
Also remove extra valueization from PRE phi-translation.
2021-11-03 Richard Biener <rguenther@suse.de>
* tree-ssa-sccvn.c (vn_nary_op_insert_into): Remove always
true parameter and inline valueization.
(vn_nary_op_lookup_1): Inline valueization from ...
(vn_nary_op_compute_hash): ... here and remove it here.
* tree-ssa-pre.c (phi_translate_1): Do not valueize
before vn_nary_lookup_pieces.
(get_representative_for): Mark created SSA representatives
as visited.
